tkinter creating buttons in for loop passing command arguments

window.mainloop()
In this piece of code basically I am creating a window where all the passwords saved in password.txt file will appear.
The code creates a button on the name of the website whose password is saved.
What I want to do is that when that button is clicked I want to get the text of the clicked button bcoz all the buttons are created automatically they have same name and the text of button is the one that is created in the last iteration.
You may pass the argument while adding click event in dynamic generated button.
for example below is your old code:
button_ = Button(frame,text = name , font = ("Helvetica", 12), width = 16, bg = "white" , fg = "black", command= create_window)
If you want to get the value of name when click on this button. Just do as like below:
button_ = Button(frame,text = name , font = ("Helvetica", 12), width = 16, bg = "white" , fg = "black", command= create_window(name))
Here i'm adding name argument in create_window function.
That i had already impletemented in my project and its working fine. Please try it and let me know if you will face any issue.
Please check below link for more details.

When the "view" button is pressed, it should trigger the function solution(i) such that label should be displayed in the new window. The problem is that the window opens and the previous label is packed but the label which gets it's text from "i" does not gets packed, Is there any issue in passing the parameter.
Any help is appreciated.

I am building a small app to study the vocabulary of various languages (see below the code for Mandarin). I have the basic funcions which work well. Now I want to add a button in my GUI where i can remove entries (i.e. individual words) from the database, once i have mastered the word (i.e. a button in tkinter which would remove the entry). After removing, the random function in python should then only select words from the reduced database. Do you have any idea how to do this? Any help is welcome!

This is not really a question about Pyxl or Excel. The question is really: how do you generate random numbers that skip certain numbers.
from random import randint
n = 592
numbers = list(range(n))
# To get a random number from the list
random_number = numbers[randint(0, len(numbers)-1)]
# To remove 123 from the list
numbers.remove(123)
does anyone know any alternatives for:
root = tk()
when i run my program, multiple windows run at the same time, just wondering whether there is an alternative so that they both dont open at the same time. The second window that opens as soon as the program is run should be launched when a button on the initial window is pressed. I also tried using:
root = Toplevel()
but the results are the same.
any ideas? thanks

this is what is meant to pop up initially but comes completely mixed up with the other one.
does anyone know any alternatives for: root = tk() [sic]
There is no alternative. A tkinter application absolutely must have a single root window. If you do not explicitly create one (and you should), one will be created for you the first time you create any other widget.
The second window that opens as soon as the program is run should be launched when a button on the initial window is pressed.
The reason for this is that you are telling it to open immediately. Take a look at this code:
Search_Inventory = Button(root_menu,
command = Search_Inventory(),
The above code is identical to this:
result = Search_Inventory()
Search_Inventory = Button(root_menu, command=result)
Notice the lack of () on the command. The command attribute requires a reference to a function.
command= needs function name - callback - it means without ()
But you have () in
command = Search_Inventory()
and this is why this is executed at start, not when you click button
BTW: tkinter need only one mainloop() - if you use two mainloop() then it works incorrectly.
EDIT: Problem with image is because you didn't set parent for Label in second window
photoLabel = Label(image=photo)
so it used main window as default
You need
photoLabel = Label(root, image=photo)
EDIT: minimal working code

I'm trying to create a program in where you put a word in a box, press add, and this word goes to a list, which is also displayed on the right side. When I press the forward button the first thing on the list is deleted. Problem is I can't get the labels to update when I press the buttons / edit the list.
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['none']
spe = speakers[0]
def add():
if spe == 'none':
speakers.insert(0, [s])
e.delete(0, END)
spe.config(text=speakers[0])
else:
speakers[-2] = [s]
e.delete(0, END)
spe.config(text=speakers[0])
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
spe.config(text=speakers[0])
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black', command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black', command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)

Is this the sort of thing you were looking for ?
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['50']
spe = speakers[0]
def add():
entry=e.get()
speakers.append(entry)
listdisplay.config(text=speakers)
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
listdisplay.config(text=speakers)
spe=speakers[0]
n.config(text=spe)
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black',command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black',command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)
listdisplay.grid(row=0, column=10)
root.mainloop()
If so:
You create a list and then you use the append function to add an item to it. The rest was pretty much right.
